Vespa 1951 Siluro

Moto-Guzzi Record

Motorcycle record breaker with 65 cc engine capacity, later increased to 73 cc. The machine was fitted with an inclined single-cylinder two-stroke engine. The aerodynamics encompassed the rider and the chassis, including the wheels. The rider assumed the aptly termed "frog position", resting his knees on the supports above the drive chain and his feet on the running boards affixed to the rear of the frame.

In 1948 the machine won numerous world records in the 75 cc class at Charrat-Saxon, Switzerland and at Monza.
